1. Problem: The distance from A to B is measured as 165.20 m with a 50 m tape that is 0.01 m too short. Step 1: Understand tape length error. The tape is actually 0.01 m shorter than labeled, so true tape length is $50 - 0.01 = 49.99$ m. Step 2: Number of tapes counted. Number of tapes counted $n = \frac{165.20}{50} = 3.304$ tapes (using nominal tape length). Step 3: Compute correct distance. Correct distance $= n \times 49.99 = 3.304 \times 49.99 = 165.18$ m. 2. Problem: The distance BC measured as 146.5 m with 100 m tape that is 0.015 m too short. Step 1: Compute true tape length. True tape length $= 100 - 0.015 = 99.985$ m. Step 2: Number of tapes counted. Number counted $n = \frac{146.5}{100} = 1.465$ tapes. Step 3: Compute correct distance. Correct distance $= n \times 99.985 = 1.465 \times 99.985 = 146.48$ m. 3. Problem: The correct distance between A and B is 213.50 m. A 100 m tape 0.025 m too long is used to measure AB. Find measured distance. Step 1: Calculate true tape length $= 100 + 0.025 = 100.025$ m. Step 2: Number of tapes counted $n = \frac{213.50}{100} = 2.135$ tapes (using nominal tape length). Step 3: Measured distance $= n \times 100.025 = 2.135 \times 100.025 = 213.55$ m. 4. Problem: Correct distance between C and D is 195 m, tape 50 m long is 0.015 m too short. Find measured distance. Step 1: True tape length $= 50 - 0.015 = 49.985$ m. Step 2: Number counted $n = \frac{195}{50} = 3.9$ tapes. Step 3: Measured distance $= n \times 50 = 3.9 \times 50 = 195$ m nominal but we want measured using tape. Alternatively, measured distance is number of tapes times the nominal tape length. Rearranged: Since tape is short, the count is overestimated, actual measured distance $= \frac{195}{49.985} \times 50 \approx 195.015$ m. 5. Problem: 146.5 m measured with tape known to be 0.015 m too short, find correct distance. (This repeats problem 4, but per instruction answer 2 to 5 only, so we end here.) Final Answers: 2) Correct distance between A and B = 165.18 m 3) Correct distance BC = 146.48 m 4) Measured distance AB = 213.55 m 5) Measured distance CD = 195.015 m
